Abstract

Chlorine dioxide solution for use in waste water treatment is produced in an automated small scale plant wherein sodium chlorate solution is reacted with sulphur dioxide at subatmospheric pressure by countercurrent flow in a reaction tower. Water ejectors are used to withdraw gaseous chlorine dioxide from the upper end of the tower and form therefrom chlorine dioxide solution and also to withdraw liquid effluent from the bottom of the tower for discharge. The plant is fully automated to form chlorine dioxide solution in response to inventory requirements. The chlorine dioxide-producing reaction is only permitted to operate if each of a plurality of sensed parameters is within predetermined ranges.
